• And fourth, is~constant monitoring of the vole of rock which would be <br />produced in the reconfiguration. This is important, because if adequate <br />mineable reserves are not available in the reconfiguration, the rest of the <br />• plan will fail because of a reduced economic advantage. This is part of the <br />trade off. Castle Concrete gets the rock and the city gets a more reclaimable <br />quarry and improved city backdrop. <br />DESCRIPTION Q$ RFSEaRru ~p ~{g~ ~g~--ODS: If the reconfiguration cannot <br />go forward for some reason, then we will be faced with the problem of working <br />with what is there. In order to improve this situation, minimal earthwork <br />would be available. Other methods would need to be found to improve the <br />revegetation environment and these would need to be carefully studied and <br />researched. But whatever is done, the main problem is how it will be paid for. <br />Without an altered plan, it is estimated the quarry will be finished in two to <br />four years. Whatever is done will have to be cheap, easily implemented, and, <br />most important, successful in a one-shot approach. At this point in time, <br />there simply does not appear to be anything which will meet these requirements. <br />Therefore, two choices seem to be available. One is re-mining and the other is <br />to do the best possible with what is there. The latter certainly does not <br />present very favorable prospects. <br />DESCRIPTION ~ OPERATION: The Pikeview Quarry is a rather large quarry on the <br />steep side of a mountain. It was first operated In the 1950's as a source of <br />rock for the construction of the United States Air Force Academy. In fact, it <br />_ has been said that the Academy was built out of this quarry. <br />Castle Concrete acquired the operatlon in the early 1970's. Prior to that <br />time it was operated for a short while by Golden Cycle and prior to that it was <br />dormant and abandoned. <br />The quarry produces a steep backwall of benched limestone. This backwall <br />is considered to be reasonably stable, but not greatly so. Unfortunately, once <br />again, the product mined produces a problem in the final configuration. This <br />problem occur as a result of the difficulty of producing square benches in <br />. 12 <br />
